The letter A, is used'to indicate the frame of our machine from whichupwardly extends the supporting columns B, B', B2, of which three areused, although more maybe if so desired These celnmns are united by armsC,;`-w`hich meet around the central hub o r vbearing D. A

' Centrally throughthe machineextends the the can bodyblank and toassure theformed can body coming directly under, or in line with, thesolder iron.

Erom the' uniting 'arms C, downwardly eX- tend the arms L, which supportthe plate M, through which centrally passes the main shaft E, as shown.This plate is held' rigid or immovable, and is provided with aneccentric grooveN, which serves to draw the expanding' rod for themandrel in or out as will be more fully set forth.

j To the periphery of lcarrying disk F, is secured a series of.depending supporting brackets O, of which anynum'ber may be employed.'By preference We use` about eight and inasmuch as each is afac-simileof theother, de

- tail descriptionbf one'will suffice.

To back i plate P of said bracket is secured a hollow vmandrel orformer, which is composed of two pa1 ts R, R. This former or mandrel isattached to said back plate by -means of a bolt or set screw S, andthrough said plate works the expanding rod T, which-extends into themandrel through the elastic cushion U, 1ocated interiorly thereinbetween the sections. The inner portion of said rodlorexpander issecured to the sliding block Vworkin g throughv the opening fornied inthe projecting flange W,of the bracket O.

To the end of the sliding block V, is secured a roll X,through medium ofpin Y. This roll fits and works within the eccentric groove- N of theplate M, consequently it is obvious vthat as -the carrying frame F isrotated, by the rotation of shaft E, the roll moves Within the eccentricgroove of the stationary platev M, and causes the sliding block Viaudthe rod P, to` move in o r out in order to expand or collapse the.mandrel for -the purposepfl causing the can body blanks to. entirelyfill the closed jaws in order to give propersize to the vessel body, orto permit the ready re moval of the formedbod'y from mandrel.

Around mandrel R, is adapted to be closed the clamp jaws for the bodyblank, in order to .frgc'e same to correspond to contour of saidmandrel. These jaws we make by preference vin three sections the lowersection a, of which is secured to plate P, of the bracket O by means of`the hinge I), and to section a, is hinged side sections c, d, asclearly shown in FigsAlZ and'lft. I These sections are raised in orderto clamp the body blanks as delivered from the feed table, by means ofrods e,f. Rodf, is provided with yoke arms h, z', which have securedthereto rollsj, Za

V`ing shaft Z, the rod e, is first raised, which contacts with undersurface of section a, and

lifts the same until the vessel body blank is firmly held against1na'ndrel,which holds said blank in a horizontal position. fter sectionraised, which ,causes the yoke arms h, fi, to move upward'and during thetravel thereof, rolls j, Zt, contact with sides of sections c, LZ,andcause the gradual closing thereof,I which The rods and clamp jaws areheld in this po- ,sition by means of roll m, secured to rod f, byshaftn, which travelsupon the trackway .0, secured to the inner face ofthe-supporting column, and the lock link g. This trackway runs for agiven distance upon a level and thence gradually declines, shown in Fig.4, in order to lower rods e, f, and allow of the clamp .jaws opening forthe purpose of permitting a, has been lifted its full distance, rod f isforces the vessel blanks around the mandrel.

the withdrawal of the completed vessel body,

from mandrel which will be more fully set forth. Faces of ljaws c,y (Z,we provide with tiles p, q, which are secured thereto bymeans of springclamps r, s. These clamp tiles prevent the faces of the jaws frombecoming worn vby contact with soldering irons, consequently savedestruction of the entire jaw, which would result in case Wear wereallowed by contact with irons. By providing removable clamp tiles we areena-bled upon wear thereof to insert others readily in place, thussaving the entire jaw. In case one tile becomes broken another mayquickly be substituted therefor. The face of mandrel section R, isprovided with projecting or raised lip t, which insures perfect meetingof blank edges in order to provide a neat seam to the vessel, besidesforming a solid bearing for soldering irons. prevented from being'withdrawn from within the elastic cushion of mandrel by'mea'ns of thelock nut u, fully shown in Figs. 16, and 17.

The foregoing mechanism is operated by means of the transverse shaft c,which has secured thereon small gear wheel w, which meshes with thelarger gear located on the.

As said shaft is rotated, motion The expanding rod T, is

IIO.

thereof is imparted to shaft Z, through the medium of the-gear wheels w,Uponthis shaft there is located a series of cams and eccentrics whichserve the purpose of transmitting motion and operating the severalfeatures of our machine, each of which will be described and fullypointed out. It must be understood that each of the cams and eccentricswork respective features and partsof the machine during rotation ofshaft Z, consequently by the hereinafter expression further rotation ofsaid' shaft (or similar expression), is intended to be understood thatas the shaft Z, continues to rotate. Both shafts o, and Z, work withinsuitable bearings formed in frame A. l

Secured to the frame by meansof straps z, is a rack bar A', the teeth ofwhich engage Awith teeth ofsegment C'. This segment is .rec

, secured loosely upon the central shaft E, by

means of thesleeve D', and is adapted to partially rotate the ratchetplate K, upon its forward movement by means of the pawl E', engagingwith ratchet teeth F'. Consequently as segment- O', moves forward apartial rotation is given to the ratchet plate which being in turnrigidly secured to the central shaft, carries the lsame therewith.Eccentric G', mounted upon shaft Z, is connected to'rack bar A', bymeans of pitman H', consequently as shaft Z, rotates, eccentric Gf', iscarried thereby and by means of pitman H', moves the rack-bar forwardand backward. As said bar moves forward the ratchet plate or wheel K, asbefore described, is partially rotated,-but

whilethe same moves backward the ratchet plate remains stationary,inasmuch as the pawl E', passes over and does not engage with teeth F'.ADuring rotation of shaft Z, cam I',

raises rodJ', working through the block K', se-V cured to the machine bymeans of the bracket L'. This rod is secured to the plate M',consequentlyas rod J', is raised or lowered by v contact with cam'ly',during its rotation, plate M', is likewise carried. As thisI plate movesupward it contacts with rod e, which sel'ves to lift clamp section aThrough the blockl K' also works thevrod N',which as raised confactswith the rodf, and causes the uplifting thereof in order to ,close theclamping jaws c, (Z. Rod N', is operated by the eccentric O', which isprovided with the groove P', into which its the pin Q', projectingthrough the slot S', cut in the block K', consequently as eccentric O',is rotated, rod lN', is raised or lowered by the projecting pin Q',which works in the slot P'.

\As before stated any number of mandrels' carry a formed vessel bodyblank from withinv front of the feed table to the soldering feed device,which being of 'usual form calls forno specic description herein. Afterwire solder has been fed to the clamp jaws, the clamped body is carriedbeneath the'solder iron T', by,V

further rotation having been imparted to the central shaft. Thesoldering iron is given a reciprocating motion through the medium of therocking lever U', which is pivotally secured `to the frame by means ofthe pin V. The rocking bar is provided with arms W', X', the end -oflwhich we secure to each of the soldering irons. ward',- the solderingiron T', is likewise moved, while the soldering iron Y', is movedoutward with, outward throw of arm W' ,thus causing reciprocation of thesoldering irons. The soldering irons are held firmly upon the 'clampedvessel body blanksby ,means-of pivotal weight t As the arm X', is thrownin.

rods Z', which are secured to the machines as shown in Figs. 8 and 9.These` rods bear firmly upon soldering irons through the medium'of rollb'.

, The usual heating chamber'o' ,is secured-t0 soldering iron T', towhich gas is supplied in the ordinary manner, which forms no part of ourinvention. The soldering irons are secured to the rocking lever arms bymeans of bar a', and. are reciprocated by means of rod d',secured to arme' of the rocking lever, and arm f' of crank lever g'. This lever ispivoted to column B, by pin h', and arm t" is connected to operating rodj', which is raised and. lowered by means of cam k', secu red upon shaft1J, and to which rod j' is connected by means of wrist pin Z',consequently as said cam rotates, rod j', is raised and lowered, whichmoves the arm f', of the crank lever in and out and likewise connectingrod d', and thusthrows arlns W', X', of the rocking lever in order .toimpart reciprocating motion to the solder irons. The soldering irons areraised and lowered upon the vessel body by means of cam c", secureduponvthe shaft Z, and which with rotation thereof contacts with rod Z",movably secured upon the shaft or The rearwardly extending portion ofsaid rod fits beneath the lifting rod m'. As cam k", during its'rotation contacts with trip rod or lever Z", the outer end thereof isthrown down- Ward, while its rear portionis raised or lifted, and duringsuch movement contacts with the lower end of lifting rod m", and raisesthe same, and inasmuch as the upper end thereof is secured tothesoldering iron mechanism,

'the same is raised clear of contact with can solderingiron-`Immediately after lifting rod A -m', starts to raise, cam n', bears uponouter end of the trip rod or lever o', inovably scoured upon .shaft c,and moves same downward, which causes inner end -to raise, and

lift rod p', and cause lock rod q', `to be freed from engagement Withthenotch r', of the lock plate J, and thus allow of rotation thereof, andthe central shaft to which the same is secured rigidly, one step. Theinner end of the lock bar'orrod g', is secured to the central shaftE,1by the sleeve s', and the outer end movablyto lifting rod m', bymeans of strap t'. Of course as the cam n',passesl'roni` contact withthe outer endo'f trip rod .0', the same raises and inner endl lowers,which allows lock rod q' to 'drop into locked engagement with the. notchof the lock plate .I, and prevent further rotation of the cen- -linewith the soldering irons. However, in

order to provide against the' jolting of the machine, which is liable toresult in bringing IOO IIO-

the rotation of the shaft to sudden stoppage,

we provide a friction clutch which is secured so as to exertagradualpressure upon ratchet wheel K, and said clutch or brake consists ofstrap. a', one end of which is attached to the frame at n', and free endpassed around pe- Ifiphery w, of ratchet wheel K, and is then secured tothe end of the weighted rod which is pivoted to brace y.- Prior'tolocked bar raising from locked engagement with notched lock plate J, camz', raises weighted rod m', which throws inner end or toe of said rodoutward, thus releasing the bindingr of strap Iupon the periphery of theratchet plate or wheel and allowing of free movement or rotation of thecentral shaft. However, ere the lock bar moves into locked Vengagementwith the lock wl1eel,camz, moves out of con-' tact with the Weightedrod, and same is allowed to fall, which throws inner end of the toeinward and causesstrap uv', tobind tightly, by friction, upon theperiphery of the ratchet wheel thus gradually stopping rotation of'thecentral shaft and overcomingsudden lstoppage by lock bar. Duringrotation of the central shaft, by the before described mechanism, andtravel of the clamped jaws toward the soldering irons, roller X, securedto the sliding frame V, travels in an eccentric groove N, of the slidingplate l\,'and during movement toward the iron, said eccentric grooveserves to drawthe sliding frame inward, and rod T, secured thereto. Theinward movement of this rod serves to compres's the elastic packing U,of the mandrel and force'eaeh section outward its full distance in orderto insure the full size to the vessel body formed thereover by theclamping of the jaws. The elastic packing is held thus compressed untiltheretained vessel body has been perfectly soldered, whence roller m,'after the clamped jaws have passed the soldering irons, enters thedownwardly inclined trackway, which causes the rods e, and f, to movedownward in order to release the jaws 0,01, and a, from the contactwith'mandrel and at the same time.

point about two-thirds the traveling distance,

the soldered vessel is in condition to be easily removed. n

To the projecting end of shaft Z, 1s secured a spirally grooved cam A2,within which works the lower end of rod B4. This rod is pivoted withinthe arms of bracket C2, and has its upper end connected to the slidingrod D2, which .works Iin frame E2. NVithin the inner portion of thesliding rod is pivoted spring actuated catch hook bars F2, G2, the upperends of which are connected to pins H2, 12, by means of. springs J2, K2.'By means of this sliding rod'we remove soldercdvessel bodies desiredreceptacle lfor4t{lief-purposey As the spirally grooved cam A2.. movesthe lower end thrown inward, which carries therewith sliding rod D2. Assaid rod somoves, hook bar F2, passes over the can vessel and in sodoing -the lower project-ing end is thrown inward,

of the vessel and is thrown backward. After the rod has passed theentire length of the can, the resiliency of spring K2, ydraws the upperend of bar F2, inward and causes the then secured between the lower endsof .bars G2, F2, and as the lower end of rod B4, movesA inward by travelwithin spirally grooved rotatingcam A2, the upper end is thrown out- D2,and consequently draws the can Vessel fromoff the mandrel.

The lowerprowhat thinner than the body portion, as shown at f5, The reduced endiits within the open quently as the vessel is withdrawn from the over,inasmuch as the end thereof bears upon the under faceof shoulder f6, andis thus held in a straight line.v

Frame A has bolted or otherwise secured outer frame or casinglM2,offeel'drmebhanisin. This casing is immovable and withinxthe saine islocated the sliding box or frame N21. 'Said box ,or frame is caused tomove forward'l/and cured at its upperend to downwardly. extend ingprojection-P2, while the lower endis pivotally secured to the bracketQ2, and the said i. rod is operated through suitable intermediate uponshaft Z.

Within the side pieces of frame M2, we cut the elongated' slots S2,within which work rollers T2, secured to the lower end of nipper armsframe N2, by meansof pins V2. These arms fare further secured to saidframe by means of springs W2, which tend to pull the upper end thereofdownward, so as to hear upon the that the elongated slots graduallyreduce in height from point 3 to y4, consequently while rollers T2, workwithin ,the reduced portion,

Withinbearings X2, works' axle 'Y2,'of the dellvery wheel Z2. Theperiphery of said wheel 1s cut away so as to providea. seriesl ofradiatln g arms as, between which' body blanks are held by means ofsprings or clips-b3.A The deliverywheel is rotated by means of the`ratchet c2, secured upon one end of the shaft or axle Y2, through themedium of pawl d3,

Isecured toarm e2 of sleeve f2. This sleeve works loosely upon shaft Y2.Pawl d2, is fastened to the frame by 'spring g2. As frame N2, is movedforward by-operation of rod O2, pm or lug h2, contacts with arm i3, ofsleeve f2, and causes same to move upward'within the slot js, andconsequently causes the sleeve to turn upon axle Y2, and throw arm e2,downward. ThisA downward throw causes pawl d2, to move over the ratchetwheel one notch. At same 4time the nipper arms move forward, and asrollers-T2, pass within the enlarged portion of the elongatedV slot,spring- W2, draws the upper end of said arm down.

ward and closes nipper ends k2, upon the upper forward end of frame N2.As the nipper arms close, the body blanks pass under and are caught by,projecting ends 7a2, and are firmly held upon the sliding frame. Withthe continued forward movement of the sliding frame the body lblank iscarried from between t-he-arms of the delivery wheel and forced totravel longitudinally between the periphery of crimp rolls Z2, m2, whichare adj ustably secured within frame n2. and are raised or lowered byset "screws o2, These rolls are provided with an oppositely beveledperiphery, and as the body blanks pass thereunder crimp or slightly bendthe edges thereof, so as to make a perfect lap when formed around themandrel. The sliding frame carries the body blank-under crimp rolls andover iiuxing wheels p2, which rotate within tank gli', which containsliquid flux bath. These rolls are mounted 4upon shafts r2, and rotatedvby means of Wheels s3, which receive motion from an endless belt t2,traveling over said wheels and roll a3. -This roll is operated by travelof belt o2, which works thereover and sprocket wheel '102, secured uponshaft-Z, Fig. l. As the body blank moves from contact with the ux rolls,it is fed beneath the mandrel or former and is compressed therearound asbefore described.

By providing projecting lip t, to mandrel we compensate for varyingthickness which may take place in body blanks, and besides allowv ofthe-crimp edges of the same fitting thereover when the clamp jaws have4been closed, consequently providing a firm seat for the soldering irons.Again byproviding the projecting lip we Vare assured of the formedblanks, when the mandrel has been expanded, being of full size, inasmuchas said lip allows or compensates for wearing of mandrel.- Upon vtravel.under the crimp rolls.

\^ this lipspring clamped tiles force t-he crimpedv edges of the blankto rest when the ,jaws are closed. It will be noticed that the bottomsof these tiles extendjoe' ow-the inner faces of the v jaws, but inasmuchas the same are held by spring clamps they will give to the pressure ofexpanded mandrel whenI jaws are clamped. However in case the mandrel orinner su'rface-of the lclamp jaws, become muchl worn, it would beimpossible for the mandrel to force the blank body suiicient to filljaws, then the downwardly extending tile answers to force thev crimpededges upon the projecting lip of the mandrel and thus secure a vessel ofproper size.

To the side of the delivery wheel/ frame is attached a gage plate m2,against which the edge of body blanks, secure within wheel, bear bymeans of the spring pressure bar 1Y2. Said plate and bar hold the blanksin true line with crimp roll, consequently as said blanks are forcedforward there is no danger of the same being moved out of line. This visan important feature o f our invention, inasmuch' as it serves toalways'maintain blanks in true line and causes each blank to bedelposited in an endwise position,thus insuring a uniform position oflap when the 'blank is formed around the mandrel by means of clamp jaws.Vithout employment of a gage plate and spring pressure bar there wouldbe a tendency of the blank being unevenly deposited,consequently anuneven feed resulting, hence preventing an exact and true lap beingformed.

Spring guide 'plate z2, overcomes the liability of moving blankscrowding during the Nipper rods IOO retain their hold onf'bodyblanks-until the sliding frame has moved suiiciently to `cause roll T2,moving withinthe reduced opposite end of the elongated slot, to releasetheir hold. When the sliding frame returns by the outward throw of rodO2, arm 2, of s elve n f2, moves downward within slo ,72, /hich movementcauses an upward thrb o' ,ari/111e?,I and the consequent .rotation ofthe/"/` /elie'r'jy/ wheel, inasmuch as pawl. d2, secure yT'to/ rml e2,engages the ratchet wheel androtates'the same one notch, and serves-tobring the next body blank in position to be moved forward to the mandrelby the movement` of the slid-/ ing frame, as before set forth. Inasmuchasthe sudden turn or throw imparted to the feed wheel has a tendency tocarry the body blank'. held thereby. below the line of the nipper izorods, we secure the friction brake thereto,

periphery of the wheel.

Our machine is set`in motion by means of the footleverE4, which whendepressed draws rod F4, inward, consequently throwing clutch G4, intoengagement with clutch 114, which rotates loosely upon shaft .itInterlocking of the clutch mechanism causes motion of belt wheel Y, tobe transmitted to shaft In, inasmuch as clutch l14, is connected tosleeve 14, upon which the belt wheel is secured. In order to stop themachine, tread lever J4, is depressed, which throws rod F4, outward andmoves clutch G4, inward out of contact with clutch H4, by means ofconnecting rod K4, all of which being of ordinary construction call forno specific description.

By the employment of our delivery wheel there is provided acontinuonsfeed of blanks to the carrying frame, thus allowing for more rapidworking, by which arrangement provision 1s made for feeding any numberof blanks, consequently after the wheel has been filled, the operatormayattend to other matystopping of the seaming machine,

ters until such timeas the wheel requires reiilling, In case any of theblanks become improperly located within the wheel, the same may beremoved or allowed to be straightened by contactwith the spring pressurerod, which forces the same against the gage plate and causes eveningwithin wheel.

. As now constructed and operated, no mechanism is provided for theraising and lowering of the soldering irons withthe starting orconsequentwhen the machine shuts down forv repairs,- or otherwise, itoftt-imes happens that the soldering irons remain down which tends toburn lthe vessel remaining thereunder. In order to guard against suchhappening,`we providev mechanism for raising or lowering the solderingirons with the start-ing or stopping of the machine. To the side offrame A, we locate shaft L4, upon which is secured sleeves M4, N4, towhich we rigidly secure gear O4, and sprocket wheel P4, and also mountupon said shaft clutch Q4, and spirally grooved cams R4, S et wheel V4,transmits its motion-to sprocket wheel P4, by means of the drive chainW4.. Clutch Q4, is connected to connecting rodK4, by means of lever armsX4, consequently as connecting redis thrown outward by vmovement of rodF4, the clutch islikewise moved upward upon shaft L4, until engagementis made with clutch sleeve M4, whence motion is' imparted to shaft L4,which is derived from sprocket wheel P4. Sleeve M4, is provided withcircular groovect4, and is connected to cam R4, by means of the slidingrod b4, the bent ends of which tit in the groove of cam and sleeve. Asshaft L4, revolves rod b4, moves within the spiral groove of cam R4,until the clutch sleeve is moved from engagement with clutch Q4,when therotation of the shaft ceases. This partial rotation of said shaft-servesto canse the rotation of cam c4, sutticiently far to Gear U4, mesheswith gear O4, and sprockbear upon arm d4, of pivoted sleeve e4,thedownward movement of which throws arm f4, upward in order toA raise rodm', which lifts the soldering irons, in manner similar to lever l. Thisraising is independent of the lift imparted by lever Z', which isalternately raised and lowered by action of cam K', during rotation ofshaft Z, and, is only for the purpose of raisingthe soldering ironsclear of the' man-y drel when the working machinery is stopped. Asconnecting rod K4, moves inward for the purpose of starting the machine,clutch Q4, is moved into locked engagement with clutch endof sleeve N4,and inasmuch as the same rotates in an opposite direction to sleeve M4,it is obvious that a reversemotion is imparted to shaft L4. Sliding rodg4, connects the grooved end of sleeve N4, lwith the spirally groovedcam S4, and serves to draw sleeve N4, from engagement with clutch L4,during the travel of the bent end of sliding rod within. the spiralgroove and thus stops rotation of shaft L4. During the movement of saidshaft cam c4 being given an opposite throw moves from contact with armd4, of sleeve c4, when the pressure of lift rod m', upon arm f 4, movessame downward and' allows said rod to lower soldering'iron. It will thusbe observed that shaft L4, is first given a half rotation in onedirection and then a reverse rotation in accordance as to whether themachine is started or stopped. l
